Fire-and-forget

This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, a laser designator) is vulnerable to attack and unable to carry out other tasks.

Generally, information about the target is programmed into the missile just prior to launch.

Some systems offer the option of either continued input from the launch platform or fire-and-forget.

As opposed to unguided RPGs which require a hard-kill system (a counter projectile(s) used to destroy the incoming missile), fire-and-forget missiles can often be jammed by means such as electro-optical dazzlers.

Many of these are infrared homing missiles; some of the remainder (e.g. AIM-120) are active radar guided.
